Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529716, here are decompositions:

47 + 31529669 = 31529716
149 + 31529567 = 31529716
269 + 31529447 = 31529716
443 + 31529273 = 31529716
467 + 31529249 = 31529716
503 + 31529213 = 31529716
719 + 31528997 = 31529716
863 + 31528853 = 31529716

Showing the first eight; more decompositions exist.
